The standard beginning of a PHP file declares the scripting language.
<?php
/* FILE NAME /musicbox/musicbox.php */
/******************************/
/* Pre-Process */
/* pre-process */
/******************************/
This section includes a number of support files. the support files are used to logically group routine sand other source code, as well as to allow multiple source files to share the same source code.
The PHP function require_once is one of several methods for sharing material from source code files.
See PHP Manual: require_once for more information.
// include function files for this application
require_once("databasefunctions.php");
require_once("visitorauthorization.php");
require_once("header.php");
require_once("menu.php");
require_once("output.php");
Collect cookie, PUT, and GET variables into $_SESSION.
See PHP Manual: session_start for more information.
session_start();
It is bad programming practice to use globals. Globals create hidden side effects.
Always use globals sparingly.
Declare a few gloabl variables to avoid proliferation of parameters.
